Ty had felt like he was missing something all morning. Just then, he remembered!
"I have to become a big sister!" He thought.
He focused on the thought.
"I wish I were a girl but I will keep my former interests and memories. Also, I wish that everyone except Dusty and myself will think I've always been a girl."
As he felt the transformation begin, he thought about the consequences Dusty would get for being a bad girl. On Saturday, Dusty had shown bad attitude, manners and little obidience. Ty could tell that she'd tryed but her temper had gotten the better of her every time.
By now Ty's body had taken on a more feminine shape. He stripped off his clothes to watch the transformation. His hands and feet grew dainty. Then his face began to change. He felt his face make some minor adjustments, just to look more feminine. His hair lengthened so it grew just above his butt, which was now slightly bigger. His chest swelled, then he looked at the space between his legs, which was currently just smooth skin. Then the privates of a girl grew within seconds. Ty was a girl.
Dusty walked down the stairs with some difficulty, her weight weighing her down. When she finally got to the living room where Ty was, she was surprised to see a girl standing naked in the middle of the room. She had been examining herself but when she heard Dusty come in she stopped.
"Hello Dusty." Said Ty. "I've decided to be nice to you. I wish that Dusty was no longer fat. I wish Dusty had bladder control and no longer had to wear a diaper."
Dusty's diaper disappeared and her fat quickly receded. Soon she was a thin 16 year old girl.
"Took you long enough!" Dusty said. "I actually look good now. I still need you to change me back to being a make though."
"Oh no!" Ty said mockingly. "Sounds like someone isn't grateful for what their big sis has done. I wish Dusty would regress in age until she were... 4."
"FOUR?!" Screamed Dusty.
But it was too late. In a single minute, Dusty had gone from 16 to 4.
"You big @$&!#%!!!" She yelled in an adorable little kid voice. Apparently her decrease in the ability to speak hadn't taken away her vocabulary.
Ty didn't realize how unfair she was being.
She was positively drunk on her power over the person who had been mean to her ever since she could remember. She let her anger get the best of her.
"I wish Dusty...!"
